RIITIIR, occasionally typeset as "RIITIIЯ," is the twelfth studio album by Norwegian extreme metal band Enslaved.

The name RIITIIR is Ivar Bjørnson's "Norse-ified" take on the words "Rites/Rituals", or "The Rites of Man", and rituals form the central concept of the album.

It’s marked by sudden shifts in tempo and disposition, propelled by unhinged rhythms: check the title track’s arabesque, Melechesh-like pummel."

They also noted that keyboardist Herbrand Larsen's clean vocals "dominate" the album, "imbuing its eight tracks with a sheen of accessibility that may test the tolerance of some.

The drumming creates a vastness, a sense of space that sounds capable of containing galaxies, but then a startlingly bare acoustic guitar passage, like the one at the end of "Death in the Eyes of Dawn," suddenly becomes intimate and lonely.

Grutle Kjellson's trademark harsh vocals find a counterpoint in Herbrand Larson's melodic clean singing, and the two styles often duel one another, caught in each other's inexorable orbit."

Several of Larsen's sections are sharp enough to be called catchy, too; indeed, throughout RIITIIR, many of the less claustrophobic moments offer a balmy respite in the midst of the spastic, ceaseless changes."
